Liquid crystal transmitters have high precision, high stability and good anti-interference ability, and are widely used in the field of industrial automation control.
A digital oil field is a fully informationized oil field. From a broad perspective, it uses information technology as a means to fully realize the digitization, networking, intelligence and visualization of oil field entities and enterprises; from a narrow perspective, it takes the digital earth as a technical orientation, oil field entities as objects, and geographic space coordinates as a basis. It has the characteristics of multi-resolution, massive data and multiple data fusion. It is a technical system that can be expressed in multiple dimensions using multimedia and virtual technology.
The concept of digital oil fields originated from digital earth. In 1998, former US Vice President Gore proposed the concept of digital earth, which caused a global shock and became one of the development hotspots in the world’s scientific and technological community. The digital oil field was created on the basis of the concept of digital earth.
Digital oilfields mainly cover geological exploration, drilling, oil and gas production, facility maintenance, production management and other links. Through data collection, processing, transmission, analysis and other technical means, real-time monitoring, prediction, optimization, control and decision support are achieved. In terms of management, digital oilfields are part of the overall development strategy of oilfields, emphasizing the digital model of enterprises and digital people as agents.
LCD transmitters are mainly used in digital oilfields to measure and transmit various parameters such as pressure, flow, temperature, etc., providing real-time and accurate data support for the digital management of oilfields.
Common faults of LCD transmitters during use include blockage of instrument pressure conduits, incorrect connection of high and low pressure conduits, poor linearity, etc. In addition, there may be problems such as the sensor zero position not coming down, sealing ring problems, wiring errors, etc.
The main reason for the blockage of instrument pressure conduits is that the medium being detected contains solid suspended particles or powders, which will solidify and block the conduit after a long time. The solution is to remove the pressure conduit for dredging.
The manifestation of incorrect connection of high and low pressure conduits is that the output value of the differential pressure transmitter does not rise, but moves below the zero scale. The treatment method is to check and adjust the installation direction of the orifice plate, or for smart transmitters, rotate the corresponding positions of the detection component and the transmission component by 180°.
The reason for poor linearity of the LCD transmitter may be the problem of the instrument itself or the error of the middle point is too large. The adjustment methods include increasing or decreasing the range, raising or lowering the zero point, etc., but if the error of the middle point is too large, it may be necessary to replace the instrument or take other compensation measures.
To ensure the stable operation of the LCD transmitter in the digital oil field, the following points need to be achieved:
Reasonably select pressure sensors and transmitters, and fully understand the working conditions of the pressure measurement system.
Install and debug according to the specifications to ensure that the pressure sensitive parts of the transmitter are axially perpendicular to the gravity direction.
Perform regular maintenance and care, including dust removal, inspection of electrical components, and calibration of output current values.
Take effective lightning protection and anti-corrosion measures to protect the transmitter from interference and damage from the external environment.
The data accuracy of LCD transmitters in digital oil fields can be guaranteed by the following points:
Select high-precision and high-stability LCD transmitters.
Perform regular calibration and verification to ensure that the measurement error of the transmitter is within the allowable range.
Monitor and record the measurement data in real time, and promptly detect and handle abnormal data.
Establish a sound data management system and process to ensure the integrity and accuracy of the data.
